Image processing for space applications
Training title:Monitoring of SPOT6 imaging performances.
Field: Operations and R&D
Speciality: Image processing
Subject
Astrium has built and launched several high resolution earth observation satellites. The last one, SPOT6, has been launched mid September and is now under in-orbit calibration and validation.
After the commissioning and delivery in orbit, Astrium is involved in the follow-on and monitoring of its satellites. This includes the functioning of the platform (thermal, pointing, power, memory, downlink,...). This also consists in the monitoring of the payload performances (noise, blurr, geometry,...) and the periodic calibration to keep the product quality at its best. Finally, it includes the investigation and answer to possible anomalies.
The proposed training will focus on the monitoring of the image quality performances during the first year in orbit. This will include:
-Monitoring of various performances (geolocation, non-uniformity,...) inside the operational "Calibration and Quality Control Office"
-R&D on improved method to monitor the performances
Depending on the planning of the internship, the contents may be adapted to be as interesting as possible.
The trainee shall have both a solid image processing background and computer programming skills (Matlab and/or C/C++).
Company background
Astrium Satellites is the European leader in the field of optical Earth Observation systems. Astrium is the pioneer company responsible for the development of the first Earth Observation space systems in Europe, starting with the SPOT family. Since this time, Astrium has led the major European developments in the fields, through programs such as METOP, ERS, ENVISAT, HELIOS, PLEIADES or SPOT6. This experience developed is now applied by Astrium on export turn-key programs such as FORMOSAT, THEOS, ALSAT and CHILI, involving a few meters resolutions systems, or such as COMS, a geostationary meteorological satellite for Korea.
This evolution conveyed Astrium to develop a strong expertise in Image Quality, Image Processing and Image Simulation through a group of about 45 engineers in 2012, constituting the Mission & Image Processing Performance department (ACE42). The Image team carries out activities in fundamental image domains such as Image simulation, Ground processing, Image quality, In-orbit testing, Embedded processing, Vision based navigation and Dedicated R&D activities.
